Are you proficient enough to survive an engine failure in your multiengine (ME) airplane today?
Unfortunately statistics say you are probably not. NTSB accident reports show that many ME pilots ignore the basic one-engine inoperative procedures learned in training, and stall/spin to their deaths.
GA multis aren’t necessarily designed to climb on one engine. We have two choices when an engine fails - maintain a safe altitude or glide to a landing. Understanding this, you must quickly revert to single engine procedures (gliding to a field, road, etc.) if unable to maintain a safe altitude.
You should establish a descending glide with both throttles in the idle position and continue the glide to a landing site to avoid losing directional control and a subsequent stall/spin accident.
Switch hats and become a glider pilot if unable to maintain a safe altitude. Gliding = Safety
